Is this what you’re looking for? I got an error on that too and I don’t have the board connected to the computer yet. I was just trying to do the first steps in the Arduino program.
Copied from error message:
Arduino: 1.8.12 (Windows 10), Board: “Arduino Uno”
Sketch uses 924 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
Serial port not selected.
This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.
